Walgreens Opens Net Zero Energy Store

The store, located in Evanston, Ill., just outside of Chicago, is expected to produce energy equal to or greater than it consumes. It will include geothermal technology, 800 solar panels, two 35-foot-tall wind turbines, LED lighting and low-energy refrigeration for food. Engineering estimates indicate the store will use 200,000 kWh per year while generating 220,000 kWh per year.

Walgreens is investing in developing a net-zero energy store so it can apply what it learns to other of its more than 8,000 stores.
